Aims and Objectives: The objective of the present study is to evaluate the surface changes like corrosion, surface roughness, micro-fractures and tensile strength of stainless steel mini plates and screws. Materials and Methods: The study was carried out at the Department of Oral and Maxillofacial Surgery, Meghna Institute of Dental Sciences, Nizamabad for a duration of 3 years. Around 34 stainless steel miniplates and 101 stainless steel screws complied to treat maxillofacial fractures of 20 patients for the rigid internal fixation were retrieved. Then the surface changes like corrosion, surface roughness, micro-fractures were evaluated using stereo microscope and scanning electron microscope whereas the tensile strength was measured using a universal testing machine. Results : The surface roughness and micro-fractures were seen in 100% of the stainless steel miniplates and screws whereas corrosion degradation was seen in 65%. Thereafter, when the tensile strength was evaluated, a mean value of 497N was found to be exhibited by the retrieved miniplates which was enough to withstand the masticatory forces. Conclusion: Through our study, we emphasize to the need for the proper handling techniques to be followed at the time of implant placements so as to avoid implants failures and occurring of other biogenic complications.

Aims and Objectives: 1. To compare efficacy of 2mm locking plates with 2mm miniplates in the fixation of mandible fractures and 2. To evaluate and compare the biomechanical function by measuring the bite force at 1st week, 3rd week, 6th week and 3rd month postoperatively in 20 patients divided equally into two study groups. Materials and Methods: A prospective randomized study was carried out at Department of Oral and Maxillofacial Surgery, Meghna Institute of Dental Sciences, Nizamabad from 2019 to 2021 to treat consecutive mandibular fractures where patients were randomly divided into two groups each composed of 10 patients where Group A  were treated with single 4 holed stainless-steel locking miniplates and Group B with two 4 holed stainless steel conventional mini plates both maintaining a gap of 2.0 mm system. Later assessment was done using bite force recording postoperatively at 1st week, 3rd week, 6th week and 3rd month and with the associated complications like Swelling, Infection, Paresthesia, Mobility between fracture fragments and Hardware failure. Results: When the mean bite force values in right molar region of group A and group B were compared at 1st week, 3rd week, 6th week and 3rd month, there was statistically significant increase in bite force noted in group A when compared to group B at 1st week and 3rd week (P0.05). When the mean bite force values in the central incisor region of group A and group B were compared at 1st week, 3rd week, 6th week and 3rd month, there was statistically significant increase in bite force noted in group A compared to group B at 1st week and 3rd week (P0.05). When the mean bite force values in left molar region of group A and group B were compared at 1st week, 3rd week, 6th week and 3rd month, there was statistically significant increase in bite force noted in group A when compared group B at 3rd week (P0.05). Conclusion: The study signifies that both the fixation systems were able to provide stability to fracture segments, but locking plate system has provided better stability when compared to miniplates system, hence recommending for more elaborative studies to arrive at definitive conclusion.   Keywords: Mandibular fracture, Biting force, Locking miniplates, Conventional miniplates.

Parotid sialoliths are very rare and frequent than that of submandibular sialoliths. However, if present they are manifested by group of clinical features such as unilateral swelling, pain whose onset and progression coincides with intake of food, etc. Even-though as there are many availing advanced diagnostic and treatment modalities like Sialoendoscopy, Lithotripsy, etc. still the conventional sialography is considered as a gold standard approach as it is not only cost-effective but also because of its increased specificity. Here we are reporting such a case of sialolithiasis of left parotid gland diagnosed and treated with conventional sialography.

The occurrence of parasitic cysts in head and neck region occurs by chance where it is commonly seen in people with varying dietary habits and life style but when it comes to oral cavity particularly buccal mucosa its preponderance is very rare and most of the times it gets confused with many of its similar group of lesions such as lipoma, mucocele, hemangioma, etc. It’s the specific investigations like ultrasonography, FNAC and biopsy which finally helps in making systematic diagnosis of these parasitic cysts. These article focuses on reporting one of such a kind of case report. Keywords: Asymptomatic swelling, Cheek region, Lipoma, Sialography, Ultrasonography, Color Doppler, Biopsy.

Inflammatory odontogenic cysts are group of lesions which has propensity to occur in any jaw, at the site of persisting odontogenic infection with radicular cysts and periodontal cysts as its common entity. However, most of them share a common treatment modalities like removal of pulpal or periodontal pathologies followed by surgical enucleation or marsupilization of the cysts where radiographic and histopathological evaluation plays a promising role not only in treatment planning but also to evaluate prognosis. Here, in these article we are presenting such an unusual occurrence of two adjacent inflammatory and non-specific inflammatory odontogenic cysts.
